Description

Technical Field [0001] The present invention relates to a wire holding device for a wire crimping machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a short wire holding device for a wire terminal crimping machine, and more particularly to a short wire holding device for a wire terminal crimping machine for holding a short wire which can not be held by a conventional wire terminal crimping machine, And a wire holding device.

In general, a wire terminal crimping device is a device for crimping a terminal for facilitating connection to an electric circuit or an electric part at one end or both ends of a wire so as to connect various electric circuits and electric parts separated from each other by an electric circuit .

In order to crimp the terminal to the tip of the wire, the cover of the wire is peeled off by a predetermined length, and then the terminal is positioned on the exposed wire and the terminal is pressed to firmly connect the wire while pressing the wire.

7, a conventional electric wire terminal crimping machine forms an elevating member 23 on the upper front portion of the casing 21 to which the driving force of the electric motor provided at the rear lower portion of the casing 21 is transmitted, 23). As shown in Fig.

The pressing member 38 is configured to press the climper 39 as shown in Fig. 8 to connect the terminal to the electric wire. At this time, the electric wire connected to the terminal must be placed on the cutter set, especially the terminal base, in a state where it is picked up by the clamping unit. Because of the interference by the cutter, the terminal is connected to both ends of the electric wire shorter than the width of the cutter, The work has the disadvantage that it must be solved only by the manual operation of the workers.

First, in the drawings, it is noted that the same components or parts are denoted by the same reference numerals as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The short wire holding device for a wire terminal crimping machine according to the embodiment of the present invention largely comprises a wire conveying means A and a terminal E for conveying a wire F and covers the wire F, (B) for connecting a terminal (E) to a conductor (the tip of a wire farthest to the front of the wire), the terminal crimping means (B) being formed at the lower end of the ram A clamping jig D for pressing the terminal E up and down according to the descent and a clamping unit 110 for holding the wire F when the clamping jig D squeezes the terminal E, And a cutter set 120 for supporting the terminal E pressed by the crimping jig D and the electric wire F so as to be cutable and capable of engaging them.

In this case, the clamping unit 110 includes a pair of rotating bodies 111 coupled to the shaft of the electric wire conveying means A and rotatable by driving means (not shown) And a wire holding portion 112 for holding the wire F.

A projection 113 is formed at a lower end of the wire holding part 112. A wire fitting groove 113b may be formed at one side of each projection 113. [

At this time, when the wire fitting grooves 113b are brought into contact with each other, a through hole through which the electric wire F can be inserted can be formed. The electric wire F can be picked up while maintaining the shape of the electric wire F and the electric wire F can be formed at an accurate position and can be stably supported .

In the present invention, a step portion 113c is formed at the lower end of the projection 113. [

In the present invention, the protrusion 113 and the step 113c of the clamp 110 are very important technical elements in relation to the cutter set 120 to be described later.

The cutter set 120 includes a support 121 having a cutter 121 that can be raised and lowered by a spring 121d and an ascending and descending groove 122a for supporting the cutter 121, The cutter 121 has a concave groove 121a formed on an upper end surface thereof and a step portion 121b formed on the bottom of the concave groove 121a .

The concave groove 121a formed on the upper surface of the cutter 121 is the most important constitution in the present invention and the concave groove 121a and the projections 113 of the clamping unit 110 constitute the electric wire F ) Is 25 mm or less, the present invention can be mechanized.

In the conventional wire holding means, when the crimper holding the wire is set on the cutter set, at least the terminal end of the wire, that is, the lead wire should be positioned on the terminal holder, and a cutter So that it is caught by the cutter. As a result, the claw portion is caught by the wire and is no longer able to approach the terminal base. Thus, it is believed that the wire bonding operation of less than 2.5 cm is impossible in the related art. Therefore, in the conventional wire holding apparatus, if the length of the electric wire is within 25 mm,

However, in the present invention, the concave groove 121a is formed on the upper surface of the cutter 121, and the protrusion 113 holding the end of the catch 110, i.e., the electric wire F, It is thin and thin enough to be interpolated so as to be as close as possible to the terminal base 123, thereby solving the conventional problems. That is, the object of the present invention can be achieved by the constitution of the concave groove 121a of the cutter 121 and the constitution of the protrusion 113 of the catch 110 corresponding to the concave groove 121a.

Therefore, the projection 113 of the clamping unit 110 preferably has a size and a shape corresponding to the concave groove 121a of the cutter 121.

A terminal support 123 and a clamp 110 for pressing the terminal E by the clamp 110 corresponding to the concave groove 121a of the cutter 121 and the concave groove 121a, The protrusion 113 holding the wire F can approach the terminal socket 123 as close as possible to the wire so that the length of the wire F is only 2.5 cm, .

The present invention is characterized in that a step portion 113c is formed at the lower end of the projection 113 and the step portion 121b of the cutter 121 corresponding to the step portion 113c of the projection 113 is provided with a step portion 121b ).

When the clamping jig D is lowered to engage the terminal E at the end of the electric wire F, the clamping unit 110 also descends. At this time, the stepped portion 113c of the protrusion 113 and the cutter 121 The projection 113 of the clamping unit 110 prevents the scraped portion of the terminal iron G from being pressed or interfered with by the step portion 121b.

When the terminal G is moved before the terminal E is pressed on the electric wire F, the terminal E connected to the terminal G is spaced apart from the terminal G by a predetermined distance. And it is inevitable that errors occur in the combination of the electric wire F and the terminal E.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the present invention is not limited thereto and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
